Open the CIPO recordAbstract From the Canadian patent
A clutch mechanism for an automatic washer is provided which permits oscillatory motion of the agitator and results in rotary motion of the basket upon no more than 360° rotation of the agitator. This mechanism is aptly suited for a planetary drive wherein a first tang is carried on a planet carrier connected directly to the agitator and a second tang is carried on ring gear connected directly to a ring gear. Engagement of the two tangs occurs upon sufficient rotary motion of the agitator wherein the basket tang will be picked up by the agitator tang causing the basket to rotate with the agitator.
